You will need:
cake batter (one box prepared according to package instructions)
marbles (rolled-up foil balls or pie weights can be used here instead)
colored sprinkles (optional)
Step 1: Fill the Pans
To create indentations in the cupcakes that will form the shape, you will be placing marbles between the pan and the lining paper. Place two close together to form the stem. Place two more spread out about 1/3 the distance between the rest of the circle (see picture).
Bake as usual.
Step 2: Cool the Cupcakes
Step 3: Frost
Ice a thin line into the "stem" section. Then spread the icing in three arches to accentuate the leaves.
Cover with colored sprinkles, if desired.
